In addition to free general admission to the gardens, admission to the Children's Garden will be free from 9 a.m. to 4 p.m. Attendees will also be able to get 20 percent off MoBOT memberships. (P.S. — you must be there in person at the service desk to get the membership savings.)

Beyond the discounts, the day will include a stilt walker, silhouette artist, and balloon artist between 10 a.m. and 3 p.m. Marionette shows will take place at 10:30 a.m., noon and 1:30 p.m.

History buffs will also enjoy the chance to learn more about Old Man Shaw with a visit to Tower Grove House, which served as the philanthropist's country home. You can explore the house that day from 10 a.m. to 4 p.m.

Free admission on Shaw's birthday has been a tradition at the Missouri Botanical Garden for more than twenty years. Other than food sales, all the activities for Shaw's birthday celebration will be free as well.
